The behringer documentation is the only source that can tell, how the commands are. You need it Some manufacturers provide two manuals: A user manual and a developing/programming manual. Check, if something like this is existing in addition. Googe for MIDI commands and if the device is able to chang...

It would be nice for others, who might have the same problem sometimes, to know, what solved it.

Other users reported such execption errorswhen launching MK2K too soon after windows start.

Describe what You are doing until You get a 90XX00 display. A screen Video would be nice.

Which entry in the log window do You click? Make a Screenshot.

Watch the tutorial videos to understand midikey2key.

I found out that the current version has a bug on this function when using a device that sends NoteOn but velocity 0 when releasing a key.
Sorry for this, it will be fixed at the next update.

That is in the FAQ. There are many methods of emulating a windows keypress. Let's say, there are 2 or 3 that are more common. Midikey2Key so far covers one of these Methods.
